SHARE Two space architects who spent 60 days living in a compact shelter in Greenland to simulate harsh lunar conditions want to design a Mars habitat for the Dubai desert next. Danes Sebastian Aristotelis and Karl-Johan So rensen were part of the Lunark mission, where they endured Arctic temperatures of minus 30°C and carried rifles for protection against polar bears . The pair work at Saga Space Architects, a company that aims to make space liveable for future travellers through approaching habitat design from a human perspective. To this end, they are eyeing the Dubai desert, because the dry climate and sandstorms are comparable to Martian conditions.
